Hi Szymos,
Thanks for the fix.
I've just try it in
Version: 6.0.0.0.alpha0+
Build ID: 6e3e4cd38b56d432c48cd7217885974e3f0519fd
CPU threads: 4; OS: Linux 4.10; UI render: default; VCL: gtk3;
Locale: ca-ES (ca_ES.UTF-8); Calc: group
and it works like a charm !!
Do not forget to close this as RESOLVED FIXED when you're done!
Thank you very much
